Abstract

The invention provides a culture method for promoting leech growth, including the following steps: 1) a culture pond is constructed; an intake pipe is installed above the left side of the aquaculturepond; an L-shaped outlet pipe is arranged below the right side of the culture pond; the L-shaped outlet pipe is horizontally arranged at the bottom of the culture pond; the L-shaped outlet pipe is vertically arranged at a vertical position; a plurality of drainage valves are arranged at a vertical position of the L-shaped outlet pipe; the inner part of an transverse position of the L-shaped outletpipe is provided with a filter screen; the bottom and surrounding of the culture pond are paved with cement to harden; 2) leech seedlings are immersed in a Chinese herbal compound and put on an artificial floating bed; 3) the artificial floating bed is moved downward along a positioning pile to submerge water pepper and eomecon in the water in the evening every 1 to 2 days; and moved upward alongthe positioning pile to make the water pepper and the eomecon grow rapidly in the morning; artificial feeds are put in every 2 to 4 days; 4) the seedlings are continuously cultured to obtain the leech. The culture method for promoting the leech growth has the characteristics of good water quality and fast growth.

Description

Technical field [0001] The invention belongs to the field of leech breeding. More specifically, the present invention relates to a breeding method for promoting the growth of leeches. Background technique [0002] Leeches, commonly known as leech, also known as leech, grow and reproduce in inland freshwater waters, and live on the blood of vertebrates or invertebrates. Leech is a traditional special medicinal aquatic animal in my country. It has the effects of "passing menstruation, breaking fatigue, and reducing swelling". It mainly treats blood stasis and amenorrhea, accumulation of malaria, and has great medical value. With the development of science, people pay more and more attention to the medicinal value of leeches. With the in-depth development of the medicinal value of leeches, its market demand potential is huge. However, the wild resources of leeches are increasingly depleted, and artificial breeding has become an important development trend at present. Leech seedli...
